    I do not understand that. Sometimes one wants connectivity from some small mobile device and there has been no replacement yet for N900 - see also some other recent article about it.

    With closed source parts of your system you can never be sure where the rare crash came from. You cannot recompile the driver with safety barriers (_FORTIFY_SOURCE, mudflap, valgrind...), hardware watchpoints trap in binary code you cannot easily verify...

    This results in unstable software commonly found on closed source platforms as nobody can provide reliable software there.

    I was using my Gecko bookmarks in $HOME but I had to create a small script to "normalize" them. Otherwise they contain a lot of useless info (timestamps, whether expanded etc.) making both history diffs useless and conflict merges difficult/impossible.

  20. Why not normal x86_64? on Firefox 3.5RC2 Performance In Windows Vs. Linux · · Score: 1
    i686 is now for about 6 years a dead horse. GNU/Linux world keeps i686 ABI compatible, that means:
    • cdecl calling convention - the stack passed arguments - terribly slow, MS-Windows world is using their stdcall/fastcall mess which is faster but not compatible with former cdecl. x86_64 uses registers passed arguments by default.
    • PIC - position independent code. GNU/Linux requires all the shared libraries (=that is all the Firefox code) to be position independent which is very expensive on i686 and as it also costs even one register. Vs. MS-Windows relocate libraries at kernel so they do not use PIC. On x86_64 the new PC-relative addressing makes PIC the same cheap as normal code.
    • 64bit data for free - 32bit code had to handle all 64bit values expensively in two registers
    • Probably other x86_64 arch improvements I forgot about. (guaranteed SSE/SSE2/SSE3/others? I do not remember.)

    Other points making x86_64 the only choice at the same time making more favors to F/OSS / GNU/Linux:

    • address space - Applications today already face the 1GB/2GB limit of i686 32-bit addressing. x86_64 has no such limits in any way. There are no reasons to run F/OSS (GNU/Linux) code in 32-bit mode. Contrary to MS-Windows with everything distributed proprietary where no 64-bit alternatives commonly exist.
    • Compiler tools development concentrates on x86_64, as proprietary code has more financial investments in the past this advantage whould vanish with x86_64 as F/OSS code has enough financial backing nowadays.

    'dd if=/dev/random of=/dev/sda'

    • Use /dev/urandom as /dev/random will immediately exhaust your kernel entropy pool and hangs to get more (or it is at least unusably slow). urandom is more than enough for this purpose.
    • There are no reports anyone would be even able to restore data after rewriting them with simple /dev/zero. OTOH rewriting by /dev/urandom and /dev/zero costs mostly the same so why to care if /dev/zero is enough.
    • cat /dev/something >/dev/sda is enough/easier on any Linux kernel, dd had to be used on some old commercial Unices nobody has seen for 30 years now.

    > If it was good enough, Linus would roll it into his distribution.

    Unfortunately one of the community successes of the Linux kernel is based on Torvald's refusal of any sophisticated code. If he could not understand it most probably 90% of the Linux kernel community also would not understand it. It would make the learning curve for the community developers too steep.

    You get more code running by 99% of unqualified developers than with 1% of the qualified ones, also due to the fact those 99% of them enjoys it as they are still learning it.

    You cannot write anything in C using just its about 5 commands/statements.
    You need to use some C system (or other) libraries and these are the compatibility problem of C.
    It is about those POSIX, SystemV, ANSI, BSD, GNU etc. etc. standards conflicting each other, with incomplete specifications etc. Also you face architectural problems of different word size, endianity etc. (this remains true even for high level languages regarding binary network protocols).
